The Fourier transform is instrumental in many signal processing applications such as digital filtering, spectral analysis and communications. In 1965, Cooley and Tukey demonstrated that the discrete Fourier transform (DFT) can be computed using the fast Fourier transform (FFT) algorithm with reduced computational complexity. When the input vector to the FFT contains mostly zeros (i.e., is sparse),...
A novel adaptive discriminative vector quantisation technique for speaker identification (ADVQSI) is introduced. In the training mode of ADVQSI, for each speaker, the speech feature vector space is divided into a number of subspaces. The feature space segmentation is based on the difference between the probability distribution of the speech feature vectors from each speaker and that from all speakers...
